Enrichment for nonhydrophobic mutants of Serratia marcescens yielded two types: (i) a nonpigmented mutant which exhibited partial hydrophobic characteristics compared with the wild type, as determined by adherence to hexadecane and polystyrene; and (ii) a pigmented, nonhydrophobic mutant whose colonies were translucent with respect to those of the wild type. The data suggest that the pronounced cell surface hydrophobicity of the wild type is mediated by a combination of several surface factors.
(i)一种无色素突变体,通过对十六烷和聚苯乙烯的粘附性测定,与野生型相比表现出部分疏水特性;(ii)一种有色素的非疏水突变体,其菌落相对于野生型菌落是半透明的。数据表明,野生型明显的细胞表面疏水性是由几种表面因子共同介导的。
